American Writers Museum—Staff Recommendation



Mary is a quiet, middle-aged woman doing her best to blend into the background. Unremarkable. Invisible. Unknown even to herself.

But lately, things have been changing inside Mary. Along with the hot flashes and body aches, she can’t look in a mirror without passing out, and the voices in her head have been urging her to do unspeakable things.

Fired from her job in New York, she moves back to her hometown, hoping to reconnect with her past and inner self. Instead, visions of terrifying, mutilated specters overwhelm her with increasing regularity and she begins auto-writing strange thoughts and phrases. Mary discovers that these experiences are echoes of an infamous serial killer.

Then the killings begin again.

Mary’s definitely going to find herself.

Praise for this book

Praise for Mary

"Mary is a book unlike any other: a serial killer thriller that’s half ghost story and half possession horror, featuring a labyrinthine mansion and a desert-dwelling cult... Mary is a late-life coming-of-age horror that shines a necessary light on a neglected character type through black humor and scenes of gloriously gross carnage."—Esquire



“Genius ... Intense ... No two readers will experience [Mary] quite the same. The reading discoveries are exciting and thrilling. Cassidy has a skilled storytelling voice capable of intense, graphic imagery and scary scenes as well as laugh-out-loud humor.”—Sadie Hartmann, aka "Mother Horror," author of 101 Horror Books to Read Before You're Murdered

“Heads up, Nat Cassidy’s debut novel is not for the faint of heart. It’s gory and horrific, but underneath the blood-soaked pages is a commentary on society’s view of older women and their place in the world.”—The Seattle Times

“Nat Cassidy’s Mary: An Awakening of Terror reads like a riposte to King’s Carrie; Cassidy has the audacity (and the skill) to write convincingly about perimenopause.”—Esquire

“Leading with one of the most unforgettable first chapters in recent horror history, Nat Cassidy . . . will rattle your nervous system from the very first page, and basically never stop. . . . One of those horror novels that will make your skin crawl while also seducing you into never putting it down.”—Paste Magazine



“Nat Cassidy’s Mary was truly dark and creepy, and a novel that clearly and unequivocally announced the arrival of a superb new voice in horror.“—Locus

“One of the best horror novels of the year, and destined to become a cult classic, Mary, like its heroine, is not to be sidelined.”—CrimeReads

“Razor-sharp horror debut.... Cassidy expertly twists the invisibility and disposability of society’s most vulnerable into qualities ideally suited to a terrifying avenging angel. It’s as scary as it is smart.”—Publishers Weekly

“This tale of horror is a good read-alike for Stephen King’s Carrie and Paul Tremblay’s A Head Full of Ghosts.”—Booklist

“[An] emerging genre star . . .”—Library Journal



“[An] outstanding debut horror novel. ... [T]he kind of debut that will surely help establish its author as one of the best new voices in horror. Mary is a fun, creepy, strange read. ... Nat Cassidy has written an impressive debut in which supernatural horror collides with real horrors, and that makes Mary the kind of novel you keep thinking about long after you’ve turned the last page.”—Locus

“Searing imagery. Immediate chills. Also, you see this cover?”—Rachel Harrison, author of Cackle



“Gripping from the start. What begins in a bloodbath leads us through decades into a nightmare of cults, ghosts, and self-hatred, where great and terrible expectations await. Mary is a devastating threat made manifest.”—Hailey Piper, Bram Stoker Award-winning author of Queen of Teeth

“Operatic and tremendously unsettling, there's a dangerous current churning beneath the pages . . . a current that will carry you far away and forever change you the way all excellent books do. This is first class horror.”—Eric LaRocca, author of Things Have Gotten Worse Since We Last Spoke

“Genius... Intense... No two readers will experience [MARY] quite the same. The reading discoveries are exciting and thrilling. Cassidy has a skilled storytelling voice capable of intense, graphic imagery and scary scenes as well as laugh-out-loud humor.”—Sadie “Mother Horror” Hartmann, author of 101 Horror Books to Read Before You're Murdered

“Who doesn’t want to read the book equivalent of vampire Kathy Bates killing some hipsters in the fifth season of American Horror Story? Middle-aged women’s rage is in this year, and I couldn’t be happier.”—CrimeReads

“Cassidy’s character-building is so incredibly complex that I can’t help but . . . make a comparison to Stephen King. . . . An extraordinary metaphor for women’s struggles, Mary is edgy as hell. A chilling compilation of horror with masterful storytelling.”—Cemetery Dance



“One of the scariest, freaky, and mind bending horror novels of 2022 and you should absolutely pick this one up!”—Horror Reads



“All I can say is, it has haunted me since I read it, and I may have to re-read it again soon.”—Horrorble Books

“There’s something here to scare even the most jaded horror lover... this book also makes a fascinating bookend to Stephen King’s Carrie as a character study of a woman at a very different stage of life.”—The Lineup



“Cassidy has given us a classic horror novel of a middle-aged woman tormented by all the little-town horrors of her past—those she can remember and those she is forced to remember. Who is Mary, or better yet, what is Mary? She has been called home to find out. A fine read.”—Elizabeth Engstrom, author of When Darkness Loves Us

“A collision of supernatural and real-life horrors, Nat Cassidy's Mary throbs with a relentlessly sinister energy. Packed with visceral shocks and quiet menace, breakneck storytelling and profound character work, Mary is absolutely riveting. I can't recommend it highly enough.”—Jonathan Janz, author of The Siren and the Specter and The Raven

“Mary, Mary, quite extraordinary... How does your novel grow? With pillow cases hiding sliced off faces, and porcelain dolls all in a row. With an acidic sense of humor more barbed than any cactus, Nat Cassidy's fast-paced Mary is a perfect blend of Stephen King's Dolores Claiborne and Frank De Felitta's Audrey Rose. This book goes out to all those bad seeds who have gone beyond their bloom and entered the twilight of their murderous lives.”—Clay McLeod Chapman, author of The Remaking

“Oh my god so Nat Cassidy’s Mary is one of the most engaging, most cathartic, and above all most fundamentally *satisfying* books I’ve read in a while. If you like scary stories you really really really need to read this one. [T]his is up there with Dolores Claiborne for me and that’s really saying something. Many cis men suck at writing women. Nat does not. Nat does NOT.”—Sunny Moraine, author of Singing with All My Skin and Bone

“[E]very bit as brilliant as everyone's saying: a gory, body horror-soaked exploration of menopause, cults, self-worth, & true crime junkies. I can't recommend this book enough—even the afterword is revelatory.”—Ally Wilkes, author of All the White Spaces

“Just finished Mary: An Awakening of Terror by Nat Cassidy & WOW! The horror arrives like a monsoon thunderstorm: ominous page 1 rumbles that build to a frenzied, spectacular conclusion that'll leave you awestruck & trembling. Smart, scary & full of heart, Mary is a force of nature!”—KC Jones, author of Black Tide

“Genuinely scary, and at times both heartfelt and heartbreaking, Mary is a powerhouse of a horror novel, with something important to say. We need more like this. Standing ovation!”—Brian Keene

“Nat Cassidy's Mary is a bravura journey into horror, cults, and the estrangement of middle age. It's one BANANAS ride, by a very talented writer.”—Sarah Langan

“Congrats on a loud and bloody Mary. She's going to make herself heard and then some.”—Kathe Koja
